SHRAPNEL.

SPECIFICATION forming part of Letters Patent No. 775,640, dated November22, 1904. Application filed February 1, 1904:. Serial'No. 191 ,693. (Nomodel.)

To all whom it may concern:

Be it known that I, PIETER DANIEL VAN Es- SEN, lieutenant of theartillery, a subject of the Queen of Holland, residing at Utrecht, 43Buys. Ballot straat, Holland, have invented new and useful Improvementsin Shrapnels, of which the following is a specification.

My present invention relates to artilleryprojectiles, and moreespecially to that kind of shrapnel-shells which contain two charges, I

one for dispersing the shot being located in a chamber at the base ofthe projectile and the second, which is only ignited at the moment ofimpact, for bursting the projectile.

The invention has for-its object to increase the effect of theprojectile at the moment ofimpact without diminishing the advantagespeculiar to the base-chamber system when it is used as a shrapnel.

in the projectiles hitherto constructed according to this plan thebursting charge was distributed over the whole lengtliof the chambetweenthis bursting charge and the exterior wall, of the projectile, partlybetween the bursting charge and the base-chamber.

1n the accompanying drawings, Figure 1 is a longitudinal section of aprojectile constructed according to my invention, and Fig. 2 across-section on line 2 2 of Fig. 1.

In the drawings, a is the exterior. skin or wall of the projectile. a

b is the base-chamber, containing the usual charge for dispersing theshot.

c is the chamber containing the bursting charge, preferably consistingof a high explosive, and e is a detonator adapted to be fired when theprojectile strikes.

g is the usual time-fuse of double action. A vent f, passing around thechamber 0 to the center of the projectile and connected to nited; butwhen the projectile strikes the detonator will fire the bursting charge0, the fore part of the projectile will first be shattered as a shell,and then the shot-dispersing charge 6 will be fired and will throw therest of the shot forward."

Having thus described my invention, what i I claim is- 1. A projectile,containing abase-chamber charge, a separated bursting charge providedwith means for igniting it at the moment of arranged partly between thebursting charge and. the exterior wall of the projectile, and partlybetween the bursting charge and the base-chamber; substantially asdescribed.

- 2. A projectile, containing a base-chamber charge, a separatedbursting charge provided with means for igniting it at the moment ofimpact, said bursting charge being located at the forward part of theprojectile and consisting of a high explosive together with asmokeproducingsubstance, and shot arranged partly between the burstingcharge and the exterior wall of the projectile, and partly between thebursting charge and the base-chamber; substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two sub:

scribing witnesses.
